What ScribeLens is

ScribeLens checks writing for AI-like patterns and gives readers both sentence-level classifications and an overall interpretation. Each sentence is marked human-like, mixed, or AI-like; flagged sentences include keywords that describe the pattern. You can paste text or upload PDF, DOCX, TXT, or Markdown files, with file extraction taking place in the browser. A scan can cover up to 40,000 words. Guest checks do not require an account and allow up to 2,000 words per scan and 3,500 words per day. For academic documents, reference lists, citations, DOI and ISSN lines, publisher boilerplate, and declarations are excluded from scoring and displayed in the report. Reports export as PDF or DOCX. Analysis stays in the browser session and clears when the tab closes, unless you create a verification link; its stored copy expires after 180 days. ScribeLens offers web and API access. The free plan costs nothing, with 35,000 tokens per month and seven PDF report exports per month. Pro is listed at $9 a month and marked launching soon.

Who it suits

ScribeLens may suit students, educators, researchers, journal editors, and content reviewers who want sentence-level assessments and exportable reports. Its API documentation also describes LMS, CMS, and editorial workflows as integration uses.

As scribelensai.com lists them, read 15 Oct 2026. The maker's own page has the final word.

Getting started

Open https://scribelensai.com/ in a web browser.
Paste text or upload a PDF, DOCX, TXT, or Markdown file.
Use a guest check for up to 2,000 words per scan and 3,500 words per day, or create an account for the Free plan.
Review sentence labels and the overall interpretation, then export a PDF or DOCX report.
For API use, obtain an API key and send it in the x-api-key header from server-side code.

Verdict

ScribeLens combines sentence-level indicators, academic-document handling, and report exports, with a free plan for initial use. Its own limitations matter: results are probabilistic, do not identify a specific AI model, and should not be treated as proof on their own.

Questions

Is there a free plan?

Yes. The Free plan costs nothing and includes 35,000 tokens per month and seven PDF report exports per month.

How much does Pro cost?

Pro is listed at $9 a month, with 300,000 tokens per month. Its status is marked launching soon.

Which platforms does ScribeLens support?

The listed platforms are web and API.

What can I upload?

You can upload PDF, DOCX, TXT, or Markdown files, or paste text. File extraction takes place in the browser.

Does it check plagiarism or identify the AI model?

No. ScribeLens says it does not check plagiarism or identify the specific AI model, and its results should not be treated as standalone proof.
